We were just called out to a house with a coal bear and the owner cant get coal to burn right in it. I think i know the problem but i am not familiar with that stove so i thought i would check here before doing anything. It looks like it has been modified the upper cast grates with the slots in have plates behind them held in place with clips welded on. It doesn't look like it is original and from what i have seen here i think i am right but if someone can confirm for me that those grates are supposed to be open i would appreciate it
